Applicant's summary and conclusion
- Conclusions:
- negative
The test substance did not induce mutations in five strains of Salmonella typhimurium, when tested up to 5000 µg/plate in the absence and presence of a rat liver metabolic activation system. - Executive summary:
Method
The study was performed to investigate the potential of test item to induce gene mutations using the Salmonella typhimurium strains TA 1535, TA 1537, TA 98, TA 100 and TA1538; the test was performed according to the OECD guideline 471, except for fact that the OECD recommended combination of strains was not respected, because none of the E. coli WP2 uvrA, or E. coli WP2 uvrA (pKM101), or S. typhimurium TA102 was tested.
The assay was performed in both with and without liver microsomal activation.
Results
The test substance did not induce mutations in five strains of Salmonella typhimurium, when tested up to 5000 µg/plate in the absence and presence of a rat liver metabolic activation system.
